Brake pads are a part of the vehicle brake system, used to increase friction, to achieve the purpose of vehicle braking. Brake pads are usually made of friction materials with wear resistance and high temperature properties. Brake pads are divided into front brake pads and rear brake pads, which are installed on the brake shoe inside the brake caliper.
The main role of the brake pads is to convert the kinetic energy of the vehicle into heat energy, and to stop the vehicle through friction generated by contact with the brake disc. Because brake pads wear out over time, they need to be replaced regularly to maintain good braking performance and safety.
Brake pad materials and design may vary depending on vehicle model and conditions of use. In general, hard metal or organic materials are commonly used to make brake pads, and the friction coefficient of the brake pads also affects the braking performance.
The selection and replacement of brake pads should follow the recommendations of the vehicle manufacturer, and ask professional and technical personnel to install and maintain. Brake pads are an important part of a vehicle's safety performance, so keep them in good condition at all times to ensure safe driving.
You can determine whether the brake pads need to be replaced in time by the following way
1. Look for warning lights. By replacing the warning light on the dashboard, the vehicle is basically equipped with such a function that when the brake pad has a problem, the brake warning light on the dashboard will light up.
2. Listen to audio prediction. Brake pads are mostly iron, especially after the rain prone to rust phenomenon, at this time stepping on the brakes will hear the hiss of friction, a short time is still a normal phenomenon, accompanied by long-term, the owner will replace it.
3. Check for wear. Check the wear degree of brake pads, the thickness of the new brake pads is generally about 1.5cm, if the wear to only about 0.3cm thickness, it is necessary to replace the brake pads in time.
4. Perceived effect. According to the degree of response to the brake, the thickness and thin of the brake pads will have a significant contrast to the effect of the brake, and you can experience it when braking.
The reasons for the abnormal sound of the car disc: 1, the new brake pad usually the new brake pad needs to be run in with the brake disc for a period of time, and then the abnormal sound will naturally disappear; 2, the brake pad material is too hard, it is recommended to replace the brake pad brand, the hard brake pad is easy to damage the brake disc; 3, there is a foreign body between the brake pad and the brake disc, which usually does not need maintenance, and the foreign body can fall out after running for a period of time; 4. The fixing screw of the brake disc is lost or damaged, which needs to be repaired as soon as possible; 5, the brake disc surface is not smooth if the brake disc has a shallow groove, it can be polished and smooth, and the deeper it needs to be replaced; 6, the brake pads are too thin brake pads thinner backplane grinding brake disc, this situation to immediately replace the brake pads above will lead to the brake pad abnormal sound, so when the brake abnormal sound, need to first identify the cause, take the appropriate measures
